Compare the2022 BMW 8 SeriesVS 2023 Nissan Z

The 8 Series’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Z doesn’t offer pre-crash pretensioners.

The BMW 8 Series has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Z doesn’t offer knee airbags.

The 8 Series has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Z doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The 8 Series offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Z doesn’t offer all-wheel drive.

The 8 Series’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Z doesn’t offer a driver alert monitor.

Both the 8 Series and the Z have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

Regenerative brakes improve the 8 Series’ fuel efficiency by converting inertia back into energy instead of wasting it. The Z doesn’t offer a regenerative braking system.

In heavy traffic or at stop lights the 8 Series’ engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Z doesn’t offer an automatic engine start/stop system.

To facilitate fast shifting and allow the driver to focus on the road, the 8 Series has a standard up-shift light to indicate when the engine is approaching redline. The Z doesn’t offer an up-shift light.

All wheel drive, available in the 8 Series, provides the best traction for acceleration in wet, dry, and icy conditions. In corners, all wheel drive allows both outside wheels to provide power, balancing the car. This allows for better handling. The Nissan Z is not available with all wheel drive.

For better stopping power the 8 Series’ brake rotors are larger than those on the Z:

For better traction and acceleration, the 8 Series has larger rear tires than the Z (275/30R20 vs. 245/45R18).

The 8 Series’ standard 245/40R19 front and 275/35R19 rear tires provide better handling because they have a lower 40 series front and 35 series rear profile (height to width ratio) that provides a stiffer sidewall than the Z Sport Coupe’s standard 45 series tires. The 8 Series’ optional 245/35R20 front and 275/30R20 rear tires have a lower 35 series front and 30 series rear profile than the Z Performance Coupe’s 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the 8 Series has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Z Sport Coupe. The 8 Series’ optional 20-inch wheels are larger than the 19-inch wheels on the Z Performance Coupe.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the 8 Series can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Z doesn’t offer run-flat tires.

The 8 Series has standard front and rear gas-charged shocks for better control over choppy roads. The Z’s suspension doesn’t offer gas-charged shocks.

The 8 Series M850i has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Z doesn’t offer an active sway bar system.

The M850i offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Nissan doesn’t offer an active suspension on the Z.

The 8 Series has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The Z’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the 8 Series’ wheelbase is 10.7 inches longer than on the Z (111.1 inches vs. 100.4 inches).

For better handling and stability, the average track (width between the wheels) on the 8 Series is 2.5 inches wider in the front and 1.9 inches wider in the rear than the average track on the Z.

The front grille of the 8 Series uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Z doesn’t offer active grille shutters.

The 8 Series has standard seating for 4 passengers; the Z can only carry 2.

The 8 Series Coupe has .7 inches more front headroom and 3 inches more front shoulder room than the Z Coupe.

The 8 Series has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Z doesn’t offer a remote starting system.

The 8 Series has a standard heads-up display that projects speed, tachometer, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Z doesn’t offer a heads-up display.

The 8 Series’ power parking brake sets with one touch and releases with one touch or automatically. The Z has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The 8 Series’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Z’s rear power window switches have to be held the entire time to open or close them fully.

The 8 Series’ rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Z’s

The 8 Series’ standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Z Performance.

The 8 Series’ standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Z has an automatic rear view mirror, but its side mirrors don’t dim.

On extremely cold winter days, the 8 Series’ standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Z doesn’t offer a heated steering wheel.

The 8 Series’ standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Z doesn’t offer dual zone air conditioning.

The 8 Series’ available Parking Assistant Plus can parallel park by itself, starting, stopping and changing direction automatically. The Z’s automatic parking system requires operating the brakes and transmission to safely park.
